Explanation:
#"the equation of a line in "color(blue)"slope-intercept form"# is.
#color(red)(bar(ul(|color(white)(2/2)color(black)(y=mx+b)color(white)(2/2)|)))#
#"where m is the slope and b the y-intercept"#
#rArry=-x+blarr" is the partial equation"#
#"to find b substitute "(10,-2)" into the partial equation"#
#-2=-10+brArrb=8#
#rArry=-x+8larrcolor(red)" in slope-intercept form"#
